Amethyst

Appearance, Uses and History

The allure of this stone has always been unmistakeable with its distinctive violet hue and tone. While there is a fairly wide range of shades, the translucent and transparent purples are considered the most valued. It can be anywhere from a very pale lavender to a dark purple. However, there is now an unusual pink form from Argentina which is technically an Amethyst too!

It is a variety of quartz, defined by its complex crystal lattice pattern and its hardness, which makes it ideal for jewellery making – measuring 7 on the mohs scale. Many semi precious rings and other forms of jewellery use cabochons cut from this stone; either as a feature stone or a decorative extra.

The ancient Greeks believed that by wearing and adorning their drinking vessels with amethyst it would prevent intoxication. This is perhaps why it has long been associated with getting rid of addictions and other destructive compulsions.

Locales

Very common, occurring in most countries to some extent – yes, even the UK. The most important commercial sources are Brazil, Bolivia, Madagascar, and Uruguay, with smaller sources in Canada, Namibia, Paraguay, Russia, and the USA,

Hazards and Warnings

Almost all rocks, minerals (and, frankly, almost all other substances on earth) can produce toxic dust when cutting, which can cause serious respiratory conditions including silicosis.

When cutting or polishing rocks, minerals, shells, etc, all work should be done wet to minimise the dust, and a suitable respirator or extraction system should be used.
